I've been looking into seat issues, too, cause after a while, my rear goes numb and gets painful........I've asked in this forum, for honest answers to the question......I've gotten several answers.......the problem is how much do you spend? you can have your seat and pilon modified for under a hundred, you can replace them for 6-800 bucks......interestingly enough yesterday I looking through the VTXOA forum andsaw that several people used the ultimate or mustang seats with the airhawk seat cushion!!!! so I am also confused.......my dealer recommended the airhawk, too.........at this point, I'm not sure what to do, myself.....cause everyone's built different and none of us will respond the same to each seat......I like the looks of the stock seat and am thinking of having it modified and adding a backrest for me........cant do that with the ultimate..........I'm starting to think the airhawk is the way to go......I've seen it for as little as $130, from Derby cycles..........
